STREET LAM P O R LANTERN SPECIFICATION forming part of Letters Patent No. 29,353, dated July 25,1899.

Application filed March 15, 1899. Serial No. 709,151. (No model.)'- I I TO 197E101": i ay eon/06TH: of a lower reservoir for the reception of com= Be it known that I, VICTOR O.

In the system of hydrocarbon-lighting to the upper portion of said hydrocarbon-reserto which the present invention appertains a'presvoir having a conduit leading thereto from sure is required in the tank containing the the compressed-air reservoir, andsaid hydrofuel in order that a proper injection maybe carbon-reservoir having a valved conduit had at the burner.

- My invention consists inthe' combination- I .J designates apipe leading'from the compressed-air reservoir B to the hydrocarbonreservoir K, which is provided with a closure L for the introduction of the hydrocarbon thereinto, said reservoir K having a valved pipe M leading from the lower portion thereof to the burner N, which latter may be of any convenient construction and supported within the globe H in any suitable manner.

' P designates arms or tubes leading upwardly from the shell E to the posts P, which support the lantern-hood Q, between the inner inclined portion R of which and the outer wall S the reservoir K is supported, said reservoir being of annular or other desired contour. 1

T designates an openended flue located above the burner and attached to the hood .Q or other suitable support, said flue receiving the end U of the chimney II and adapted to permit the latter to be raised thereinto.

The portion G, upon which the globe H is supported, has arms V extending therefrom to which are attached the sleeves WV, which carry the spring-actuated pins X. When it is desired to light the burner, it is only necessary to raise the portion which supports the globe, the arms V, and their adjuncts until the pins X engage the recesses Y, whereupon the burner is readily accessible. It has been deemed unnecessary to describe or show in detail the construction of the spring-actuated pins X, since the same will be familiar to those skilled in the art.

The posts P depend from the lantern-hood and are preferably hollow and have secured therein the rods Z, which latter enter the seat or sockets A and are held in position by the set-screws B or similar devices. The pipe J is provided with a coupling 0 and a valve D, which is usually dispensed with, it being understood that said valve is open (1 uring the operation of the device, whereby an equalization of pressure is attained drocarbon and compressed-air reservoirs, as has been explained. When it is desired to remove the hood or upper portion of the lantern, it is only necessary to uncouple the pipe J and loosen the set-screws B, whereupon the hood, posts P flue T, and their adjuncts can be readily lifted, as is evident.

The operation is as follows: The reservoir Bis filled with compressed air through the inlet-O, and the reservoir K is also filled with hydrocarbon through the inlet L, the valve in the pipe M being closed when said reservoirs are being filled. It will be evident that upon proper manipulation of the valve in the pipe M the hydrocarbon under the pressure of gravity and compressed'air will be conducted to the burner N, and by the means hereinafter described a lamp or lantern can be equipped so as to burn for a certain predetermined period, the apparatus thus being especially applicable for lighting plants of every description.

It will be apparent that the compressed-air reservoir B is utilized both to contain the pipe leading between the hycompressed air and to serve as a base for sup porting the shell E and the globe H, thereby not detracting from the appearance of the lamp, and by providing the compressed-air reservoir with the socket D the same is adapted to be readily placed in position upon existing lamp-posts Without necessitating any change in the connection thereof.

It will be evident that the construction above described is equally well adapted for use as a lantern or portable lamp, in which case the bottom of the reservoir B can be shaped, if desired, so as to afford a suitable base upon which the lamp or lantern can be set. The shell E is secured to the reservoir B in any suitable manner, a plate being interposed in practice between said shell and reservoir.

Having thus described my invention,what I claim as new, and desire to secure by Letters Patent, is

1. In a street lamp or lantern, a lower reservoir for the reception of compressed air 10- caled at ornear the junction of the lamp and its support, an upper reservoir for the reception'of hydrocarbon, a conduit common to said reservoirs, and an independent supplypipe leading from said hydrocarbon-reservoir to a burner, the latter being suitably supported and inclosed below said hydrocarbonreservoir. ,4
